[tor-dev] .i2p address support in torsocks

as I have said on the tor-dev channel, if you guys want a unique IPv4
address on a virtual machine I still have both available for you good
people. It simply takes a gentle prod in the ribs for me to enable it and
you can use and abuse it in any way wish you need.
